Coal which burns like a candle when ignited is called :

  • A.Boghead coal
  • B.Cannel coal
  • C.Lignite
  • D.Anthracite

Answer: B

Coal that burns like a candle is Cannel coal.

Cannel coal is a fine-grained, dull, massive sapropelic coal rich in spores and volatile matter. It lights easily and burns with a bright, steady, smoky flame like a candle, and its name comes from an old English form of 'candle'.

Boghead coal (torbanite) is the related algal sapropelic coal, rich in oil but not the one named for the candle. Lignite is a low-rank brown coal and anthracite a high-rank coal that burns with a short, smokeless, almost flameless blue flame.
